Ordinary aluminum hydroxide, not dried, can be used as an important raw material for aluminum fluoride, activated alumina, aluminum hydroxide re solution, high-temperature alumina and glass, and accelerator. For the re dissolution of aluminum hydroxide, it can be divided into using hydrochloric acid to dissolve and make water purifiers, using liquid alkali to re dissolve aluminum hydroxide to make micro powders, using sulfuric acid to dissolve and make aluminum sulfate, and using drying and grinding to make aluminum hydroxide fillers. Aluminum hydroxide fillers are widely used in coatings, fiber cement boards, inorganic flame retardants, and other fields.
In addition, in ceramic glaze and enamel glaze, aluminum fluoride is an ideal raw material for convenience. In the industries of structural ceramics, refractory materials, polishing materials, and electronic equipment, calcination α- Alumina powder (rotary kiln) products made from alumina and ball milling are widely used.
